Jane Says

 I wish I could remember who recommended The Veil (2016), because it was a big hit with Ms. Spenser. I want to see what else they like,

It starts with some old news footage of a cult leader (Thomas Jane) documenting his cult, Heaven's Veil, and then the aftermath of the mass suicide that must follow. Jane plays "Jim Jacobs" very much as Jim Jones (same aviator sunglasses, for ex) with a touch of Jim Morrison sex appeal. This flashback ends with one child left alive, who says to the FBI, "Don't worry, they are coming back."

In the present, this little girl is grown up Lily Rabe. She has been asked to participate in a documentary about the cult, and she finally agrees. The doc is being made by Jessica Alba with a crew of six or so. They get to the creepy compound, miles from civilization, and start looking for the films and videos that they know were taken, but were never found.

They camp out, and wake up in the middle of the night to find that one of the grips has taken off with the van, leaving them stranded. In the morning, two of the crew start walking back to civilization - nearest road is ten miles, nearest town another twenty. They won't be back before dark. 

That day, Rabe leads them to a house hidden deep in the forest. This is where all the films are. The generator still works, so they start to watch. Experiment #1 shows Jane taking a lethal injection, then being revived with some kind of powers. Each film they watch shows a little more about Heaven's Veil: Jane wants power over limitless life. When dead, he can inhabit someone else's body, then be revived.

The couple who were walking to town come back to say they found the van, wrapped around a tree, with the driver dead. That driver later comes back to life and kills them. The generator goes out, and the guy who goes to fix it gets killed too. But these dead people then show up perfectly fine, and nobody else notices they were gone. Have they been possessed? (SPOILER - yes.)

This has got a little bit of a lot of horror tropes: haunted houses deep in the woods, death cults, possession, found footage. Even vengeance, since it turns out that Alba's father was one of the FBI agents that found the dead cultists, and he killed himself shortly after. It's a little slow, and not that gory, although there's a decent body count. But it has great atmosphere, and a hell of a performance by Thomas Jane.
